Struct AprV2Flags 

pub struct AprV2Flags(/* private fields */);

APR v2 feature flags (16-bit for expanded feature set)

Implementations

impl AprV2Flags

pub const LZ4_COMPRESSED: u16 = 0b0000_0000_0000_0001

Payload is compressed with LZ4

pub const ZSTD_COMPRESSED: u16 = 0b0000_0000_0000_0010

Payload is compressed with Zstd

pub const ENCRYPTED: u16 = 0b0000_0000_0000_0100

Payload is encrypted (AES-256-GCM)

pub const SIGNED: u16 = 0b0000_0000_0000_1000

Has digital signature (Ed25519)

pub const SHARDED: u16 = 0b0000_0000_0001_0000

Model is sharded across multiple files

pub const QUANTIZED: u16 = 0b0000_0000_0010_0000

Tensors are quantized

pub const HAS_FILTERBANK: u16 = 0b0000_0000_0100_0000

Has embedded filterbank (for Whisper models)

pub const HAS_MODEL_CARD: u16 = 0b0000_0000_1000_0000

Has model card metadata

pub const STREAMING: u16 = 0b0000_0001_0000_0000

Supports streaming/chunked loading

pub const HAS_VOCAB: u16 = 0b0000_0010_0000_0000

Contains vocabulary/tokenizer

pub const LAYOUT_ROW_MAJOR: u16 = 0b0000_0100_0000_0000

LAYOUT-002: Tensor layout is row-major (REQUIRED for valid APR files) All APR files created after LAYOUT-002 must have this flag set. Pre-LAYOUT-002 files without this flag are assumed row-major.

pub const LAYOUT_COLUMN_MAJOR: u16 = 0b0000_1000_0000_0000

LAYOUT-002: Tensor layout is column-major (FORBIDDEN - Jidoka guard) If this flag is set, the APR file is “dirty” and must be rejected. This flag exists to catch improperly converted GGUF files.

pub const fn new() -> Self

Create new empty flags

pub const fn from_bits(bits: u16) -> Self

Create from raw u16 value

pub const fn bits(self) -> u16

Get raw bits

pub const fn contains(self, flag: u16) -> bool

Check if flag is set

pub const fn with(self, flag: u16) -> Self

Set a flag

pub const fn without(self, flag: u16) -> Self

Clear a flag

pub const fn is_lz4_compressed(self) -> bool

Check if LZ4 compressed

pub const fn is_zstd_compressed(self) -> bool

Check if Zstd compressed

pub const fn is_encrypted(self) -> bool

Check if encrypted

pub const fn is_sharded(self) -> bool

Check if sharded

pub const fn is_quantized(self) -> bool

Check if quantized

pub const fn is_row_major(self) -> bool

LAYOUT-002: Check if row-major layout flag is set

pub const fn is_column_major(self) -> bool

LAYOUT-002: Check if column-major layout flag is set (should be rejected)

pub const fn is_layout_valid(self) -> bool

LAYOUT-002: Validate layout is safe for inference Returns true if the file is row-major or pre-LAYOUT-002 (assumed row-major) Returns false if explicitly marked as column-major (dirty APR file)
